有無人可以翻譯同解釋呢段野比我聽啊??

When diverging light rays enter our eyes,our brain perceives the light by extending the rays backwards.If the extended rays meet at a point ,they are perceived as coming out from this point.
更新1:

Suppose a lamp is placed in front of a plane mirror.Rays of light are sent from the lamp in all directions.Rays diverge from the lamp,and on reflection diverge from the mirror. These divergent rays appear to come from a point behind the mirror.

更新2:

An observer sees the image of the lamp at this point.Rays do not actually come from the image, so the image is called a virtual image.It cannot be projected on a screen. The rays and the image are virtual ang are represented by dotted lines. 求大家解釋下呢段野比我知啊?我要做project,但系唔識得解

更新3:

可以用再寫一段與這段文字意思相同但系用字唔一樣的段落嗎??

✔ 最佳答案
當分流的光線進入我們的眼睛時,我們的腦子通過向後擴大光芒察覺光。如果延長的光芒見面在點,他們被察覺如來自這點。


假設燈在平面反射鏡前面被安置。光從燈四面八方被送。光芒從燈分流和在反射從鏡子分流。
這些分歧光芒看上去來自點在鏡子之後。

觀察員這時看燈的圖像。光芒實際上不來自圖像,因此圖像稱一個虛象。它在螢幕不可能被射出。


光芒和圖像是真正ang由虛線代表。

當被發散的燈光進入我們的眼睛,我們的腦感受到光並把它們向後伸延。如果這些被伸延的光匯於一點,它們便會被理解是從這點發放出來。

Suppose a lamp is placed in front of a plane mirror.Rays of light are sent from the lamp in all directions.Rays diverge from the lamp,and on reflection diverge from the mirror.
These divergent rays appear to come from a point behind the mirror.

假如把燈放在一面平鏡前,燈光從燈向四方八面發放。光自燈發散,並從鏡反射發散。看來這些發散的光就像是來自鏡後的一點。

An observer sees the image of the lamp at this point.Rays do not actually come from the image, so the image is called a virtual image.It cannot be projected on a screen.

The rays and the image are virtual ang are represented by dotted lines.

觀察者在這點看到燈的影像。光並非實際來自這影像,所以這影像被稱為虛擬影像。它不能投影在銀幕上。

光和影像均是虛擬的,並以虛線代表。

當分歧的時候,光光線進入我們的眼睛,我們的腦藉由向後延伸光線感覺光。如果廣大的光線在點見面,他們當做脫離這點被感覺。
假如一個燈在一面平的鏡子之前被放置。光的光線被從燈往四面八方送。光線從燈分歧,而且在反映上從鏡子分歧,這些分歧的光線似乎來自在鏡子後面的點。
一位觀察者此時見到燈的影像。光線不實際上來自影像,因此,影像叫做一個虛擬的影像。它不能夠在一個螢幕上被計畫光線和影像是虛擬的 ang 被虛線代表。
